When I was young, I would get bored at school. I once had a teacher who hated the words â€œbored,â€? â€œboring,â€? and â€œboredom,â€? insisting there was no reason for any of us to say them â€“ we either needed to think up ways to make the situation a little more interesting, or try taking interest in what we were supposed to be doing.

Maybe she had a point, but now it doesn't matter. The Internet has made boredom obsolete. There are enough web pages and enough people making new pages every day that even if we limit ourselves to the subset that is actually interesting, we will never see it all.

But, you protest, you have Firefox and a DSL connection and you still get bored? Below are four things guaranteed to make boredom obsolete.

StumbleUpon.Â StumbleUpon is a toolbar for Firefox (and now IE) that lets you channel surf the web.Â You click the Stumble button, it brings you to a web site, and you give it a thumbs-up or thumbs-down.Â Based on what other people like and dislike, it will send you to sites you should like.Â Warning:Â it is addictive.Â (http://www.stumbleupon.com/)

Wikipedia.Â Between articles featured on the main page, looking up things I've heard about but don't have any background in, and going to random pages, I can waste hours on Wikipedia.Â The "what links here" link can be a lot of fun (if you are a nerd). Â (http://en.wikipedia.org)

Digg, Reddit, and similar sites.Â I find Digg to be better for geeky tech stuff, funny videos, cool flash games, political outrage, and nerdy fanboyism.Â Reddit seems to be populated by a more discerning crowd, with more articles explaining things, news stories from mainstream media, geeky tech stuff and political outrage.Â (http://www.digg.com/)Â (http://reddit.com/).

Honorable Mention: Google Scholar. When I was an undergrad, I would go the the basement of the library where they kept the journals looking to photocopy a few articles for a paper, and end up spending hours down there. There is nothing quite like paging through a bound volume of Natureâ€”even if you can't understand much past the abstracts, research is so damn interesting!

Google Scholar is the thing I wish I had all through college. It makes finding academic literature actually easy and convenient. Why doesn't it make my list? Because far too often you are only able to read the citation and perhaps the abstract without paying $35 per article or some other ridiculous fee. If you are a college student, your school may have access to many of these research databases, but if not, you're SOL. I have no problem paying for content, but no one can afford tens of thousands for subscriptions to 20 journal publishers, and $35, or $55, or more for access to one article is the most ridiculous thing I've ever heard of.
